【Abstract】 The regression orthogonal test approach can be used to optimize the control parameters for nonlinear systems. Because in this approach the orthogonality is used for rational arrangement of the test, the number of the tests is greatly reduced. Then the least square method is adopted to establish the regression function between the control parameters and the objective function. Based on the regression empirical function, the dynamic performance can be predicted and controlled. This method has been applied to the optimization of the control parameters of a water turbine governing system and the simulation results show the method is effective.更多还原
